Is it possible to create a voice command attachment for an iPhone 5?

For a senior project at school, I would like to create an attachment for an iPhone 5 that would control the music, without having to press a button like Siri. For example, while listening to music, I would say "pause" and the music would pause, or "mute" and it would mute. Very much like in the iron man movies when tony stark says mute to the tv, it mutes. This attachment would be plugged into the headphone jack. If anyone knows where this has been already created it would be awesome if you could tell me, or if you know how I could do this.

How to get a passcode screen to appear on my IPhone 4 S?

Help! I'm unable to get to a log-in screen on IPhone 4 S. I slide to unlock. The phone then goes to the icons screen and states "SEARCHING" in the top left-hand corner. I can't telephone or search the internet because my IPhone is not connected to the internet. Does anyone know how to fix this? I created an account and it worked fine 1 month ago. I didn't use the phone for 1 month, and now this problem started when I powered the phone on. My subscription should be good for another year.

Iphone - whited00r won't work?

Ok so i found out about this whitd00r software which allows your old iPhone like 2gs, 3gs etc. To be up to date with apple. So i downloaded whited00r for my Ipone 2g which at the time had the os 4.2.1 (i don't know how) because usually its 3.1.3… But the higher the os the better right! This phone was bought in America but i'm not in america now so i had to unlock it. When asked the option of getting whited00r unlock or normal i clicked normal because to me my phone WAS normal i didn't know i was suppose to click unlocked version. Yeah so i downloaded the normal version and i didn't create a back before on iTunes simply because it wouldnt do it an i didn't really want a backup. So the software whited00r 6 normal was installed on my iPhone 2g then it said i should connect to iTunes… I did and then it says my sim card is not supported (what does the sim card have to do with iTunes smh) now i don't know what to do i tried to use redsnow and tried to enter dfu mode but it won't work because every source tells me that i need to go to iTunes plug in my iPhone an restore it but iTunes won't even lead to the restore page it just goes to that same whited00r page about sim not supported… Is there any way i can downgrade back to 3.1.3 / 4.2.1 or if i can unlock this current ios 6 from whited00r
